How Dover, NJ Weather Affects Your Foundation

It builds slowly — but the deterioration that results get more expensive the longer they continue.

Soil Conditions & Foundation Types in Dover, NJ

The soil composition in the Dover, NJ area directly determines how water behaves near foundations. Clay-dominant ground conditions, which are prevalent throughout much of NJ, hold water for extended periods and push it sideways against below-grade structures. Identifying your specific soil type changes everything about what solution will actually work.

Dover and surrounding Dover, NJ communities contain buildings from multiple eras with very different waterproofing realities.
